The rule is, "1st get it right, then make it fast." If you did a poor
job up front, you didn't get it right 1st. And usually no amount of
small, local optimization such as the OP is discussing will help you.

That's pretty much the definition of premature optimization: extra
(sometimes substantial) effort spent on obfuscation "for speed", done
early, without any measurements to indicate that it will help.
